A Compact Wideband Slotted Patch Antenna for Wireless USB Dongle Application
|Related article at Pubmed, Scholar Google|
Design of Compact planar wideband antenna suitable for wireless universal serial bus (USB) dongle application is proposed in this communication. By simply cutting notches and engrafting types of slots into a rectangular patch introduces multiple resonances. When these are combined together, the bandwidth gets enhanced. The proposed microstrip patch antenna has wide bandwidth with 10-dB return-loss and covering the range from 4.8768 to 8.9523 GHz. 59% of bandwidth could be achieved with the aid of simple microstrip Line feeding technique with VSWR<2. These features make them very suitable for wireless local area networks (WLANs) applications. This design has an overall size of only 11× 15 ×0.8 mm3 and is very suitable for use in an USB device.
